Biohazard Symbol - Universal Warning Sign for Biological Hazards #58632 (License: Personal Use)

This high-contrast red-on-white biohazard symbol is a standardized warning sign used globally to indicate the presence of biological substances that pose a threat to human health, such as viruses, bacteria, or genetically modified organisms. Created in 1966 by Charles Baldwin at the U.S. Centers for Disease Control, its distinctive trefoil shape ensures immediate recognition even without text. It appears on lab equipment, medical waste containers, and quarantine zones to enforce biosafety protocols.

This image is commonly used on safety signage, educational materials, medical websites, and regulatory documentation to communicate biological hazard warnings. It matches user intent for understanding hazard symbols, biosafety training, or designing compliant labeling systems.
